7results about "Knife-edge bearings" patented technology

An apparatus is provided that includes a diamond bearing surface positioned in sliding engagement with an opposing bearing surface of a diamond reactive material. The opposing bearing surface is hardened via a material treatment.

A power transmission system is provided that includes a polycrystalline diamond power transmission surface engaged with a diamond solvent-catalyzed power transmission surface. A power transmission system includes a first component having at least one power transmission surface thereon comprising polycrystalline diamond, and a second component having at least one opposing power transmission surface comprising a material containing at least 2 weight percent diamond solvent-catalyst based on the total weight of the material, the first component being movably coupled to the second component such that the polycrystalline diamond is engaged with the diamond solvent-catalyst and such that movement of one of the first and second components drives movement of the other of the first and second components. The power transmission system may be or include gears, universal joints, or other power transmission systems or components.

Linear bearings assemblies are provided that include polycrystalline diamond bearing surfaces that are engaged with diamond solvent-catalyst bearing. Also provided are methods of making and using linear bearing assemblies.

Power transmission systems are provided that include polycrystalline diamond power transmission surfaces that are engaged with diamond solvent-catalyst power transmission surfaces. The power transmission systems may be or include gears, universal joints, or other power transmission systems or components.
